Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0023] Such as figure 1 As shown, the present invention provides an optical system of a virtual reality device, including optical units, and each optical unit sequentially includes an absorbing polarizer 2, a display screen 3, and a 1 / 8 or 1 / 4 wave plate from the side of the human eye 1 4 and mirror 5, where,
[0024] The absorbing polarizer 2 , the display screen 3 , the 1 / 8 wave plate, and the 1 / 4 wave plate 4 (phase retarder) are all optically transparent components, and the light emitted by the display screen 3 is linearly polarized light. Here, in this embodiment, the transparent display screen is arranged between the reflector and the human eye, and polarizing devices and 1 / 8 or 1 / 4 wave plates are respectively arranged on both sides of the display screen, and the display screen is set to be transparent, which can After the virtual content is reflecte...
